Internal loopback
test
An internal loopback test checks internal port, serializer, and
deserializer circuitry and checks for the presence of an optical
transceiver, but does not check fiber-optic components of the installed
transceiver. Operation of the attached device is disrupted during the
test. To perform the test:
1. Notify the customer that a disruptive internal loopback test is to
be performed. Ensure the customer’s system administrator
quiesces Fibre Channel frame traffic through the port, and sets the
attached device offline.
NOTE:
A small form factor pluggable (SFP) optical transceiver must be
installed in the port during the test. A device can remain connected
during the test.
